Well I bought mine from a usa co I use to but tabs to help pn I however if you Google compression boots they are on sale from around 80 to 90 sterling like everything else one can pay 10 times that but these I believe are for fit athletes mine just cover the feet and legs up 2 my knees I put them on twice a day 30 mins to 40 max per time especially helpful to me at night there are a few health warnings re people who should not use these you need to check this for yourself or your doc I hope this helps my pn is still there but not so much at night and I think it's slightly easier during g the day I also walk one hour a day and swim 30 mins good luck james
